REMOTE CONTROLLED CURTAIN SWITCH Filed Dec. 1, 1930 Patented June 7, 1932 UNITED STATES 1 FRED K. SNOW, OF LYNNFIELD, MASSACHUSETTS REMOTE CONTROLLED CURTAIN SWITCH Application filed. December 1, 1930.

The present invention appertains to new and useful improvements in remote controls for curtains, and more particularly to a control for the usual curtains on the rear windows of closed type automobile bodies.

The principal object of this invention is to provide a remote control whereby the curtain of the rear window of an automobile can be conveniently controlled.

Another important object of the invention is to provide a remote control for curtains of the type specified wherein the curtain can be adjusted to any position desired.

A further object of the invention is to provide a novel switch for controlling a motor driven curtain, whereby the curtain can be adjusted to any position desired.

These and other important objects and advantages of the invention will be apparent to the reader of the following specification.

In the drawing Figure 1 represents a fragmentary inside elevational view of the rear portion of an automobile body, showing the improved ourtain associated with the window thereof.

Fig. 2 represents a vertical sectional view taken substantially on the line 2 2 of Fig. 1.

Fig. 3 is a diagrammatic view showing the electrical connection between the electrical devices involved.

Fig. 4 is an elevational view of the switch whereby the curtain is controlled.

Fig. 5 represents a cross sectional view of the switch takensubstantially on the line 55 of Fig. 4.

Fig. 6 represents a cross sectional view of the switch rotor taken substantially on line 66 of Fig. 4.

Referring to the drawing wherein like numerals designate like parts, it can be seen that numeral 1 represents the rear portion of an automobile body with the usual rear window 2, mounted therein.

The curtain bore is of the roll type, and is supported by the bracket 6 at one end and the housing 8 at its opposite end, the said housing being suitably secured to the body 1. This housing 8 embodies an electrical motor 10, the armature shaft 12 of which drives the Serial No. 499,345.

worm 14 meshing with the gear 18 on the shaft 16 of the curtain roll.

At each side of the window 2 is a guide strand 20 extending through the eye members 22 on the curtain stick 24. Thus, the curtain is guided in its vertical movement and it can be seen hereinafter, that the ends of this stick serve as an element for operating the switches 26 and 28, respectively, at v the upper and lower ends of the window 2.

Referring now to Fig. 4, the novel switch for controlling the curtain can be observed. This switch is generally referred to by numeral 86. The same includes a base to which the U-shapcd bracket 64 is secured, for rotat- 65 ably supporting the rotor 74. This rotor 74 is of some suitable di-electric material. At one end of the rotor 74 is a flange 39 of some suitable dielectric material carrying the contacts 58 and 60. It can be seen in Fig. 6, that three sides of the rotor 74 have plane surfaces, while the remaining sides, that is the neutral side is substantially curved.

On one side of the rotor 74 are the contact sections 68 and 70, while on the opposite side 75 of the rotor are the contacts 7 2 and 66. The contact 68 is only in the path of the contact finger 46, while the opposed contact section 66 is in the path of both the fingers 46 and 48.

The contact section 72 is only in the path of 8 the contact finger 50, while the contact sec tion 70 is in the path of both finger 50 and finger 48. Leads 56, 52 and 54 extend from the fingers 46, 48 and 50 respectively, to connect to the motor 10 and to the battery supply.

For engagement with the contact 58 is the spring finger 42, while a spring finger 44 is in the path of the contact 60. Extending from the fingers 42 and 44 are the leads 38 and 40 respectively, extending to the limit switches 28 and 26.

The shaft on which the rotor 7 4 is secured, is equipped at one end with a knob whereby the rotor can be actuated.

Reference is now made to either one of the switches 26 or 28. The switch 26 is detailed in Fig. 2, and as shown, includes the separable elements 30 and 32 supported on a base plate at 34. The limit switch 28 is constructed in the same manner, and obviously, when the stick 24 engages into either one of these limit switches, the motor circuit is broken,

although the same can be re-established by 5 actuating the novel switch structure 36.

Furthermore, it can be seen that the triple action of the switch and the double action type of motor permits the motor to be energized for operating the curtain even when one of the limit switches is broken.

In operation, the switch 36 is operated, so as to energize the motor disk so that the mo tor will operate to lower the curtain 4. The curtain can be stopped at any point above the contact 28, by releasing the switch 36, that is by moving the same to a neutral position (see Figure 6) but if the curtain is permitted to ride all the way down to engage the switch 28 and break the same, the motor will be deenergized, so that the curtain will remain in a completely lowered position while the motor is inactive.

By actuating the switch 36, so that the motor 10 will be operated in the reverse direction, the curtain 4 will be driven upwardly and unless the curtain is stopped by moving the switch 36 to a neutral position (see Figure 6) the same will ride upwardly until it engages the switch 26, whereupon the motor circuit is broken.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the size, shape and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having thus described my invention what I claim as new is 40 A switch comprising a bracket, a rotor mounted on the bracket, contacts on the periphery of the'rotor, stationary contacts on the bracket for engagement with the peripheral contacts of the rotor, a current supply line, a pair of leaf spring contacts on the bracket, a pair of contacts on one end of the rotor, one of said last mentioned contacts being adjacent the longitudinal axis of the rotor, while the other contact is adjacent the periphery of the rotor, one of said leaf springs being engageable with the contact adjacent the longitudinal axis of the rotor, and the other leaf spring being bent to avoid the other leaf spring and is engageable with the outermost contact at the end of the rotor, said current supply line being interrupted by the cont-act at the end of the rotor, and connections between the contact at the end of the rotor and the contact on the periphery 60 of the rotor.

In testimony whereof I aflix my signature.
